This invention relates to integral wheel bodies, disks and rims, andespecially to rims v peripherally divisible for the purpose of demanythe well known ways.

- mounting of the tire. But quite obviously it 7 has otherapplications,for exam le-ixrims hav- I ing sim 1e removable flanges 00 ed on in Itsobject is the evolution of abetter of such type, better byreason ofsimple and more stur desirable sections are the more rigidly andstrongly anchored together, better because the disk and rim connectionsare improved, and better because more economical 1n production.

The aims of my invention I attain by in tegrally rolling the disk andone of the peripheral rim div'islqns, but moreimportantlyby providing arollipg integrally with the tapered-main body of the diskand integralradially extending peripheral portion of thickened cross section,

extending thickened section," integrally formgortionflof. the rim fromthis radial 1ng one g section, and removably mounting thickene thecomplemental rim portionupon the thickened section and seating it on thebead. Such a structure is especially we ll-adapted for pro-' ductionupon an obtuse angled rolling millin connected together, and may beformed y same rolling operation. 1

7 Of the drawings which show my embodiments,. I v I Fig. 1 is asideelevation of a wheel embodying my invention, 1

Fig. 2 is a radial cross section substantially on line 2-2 of'Fig. 1,.Fig. 3 is a side elevation of a modification, and 4 I Fig. 4 isa crosssection on line 4-4 of Fi .3. v

Fig. 5 isa modification of the removable rim section. 0

The tapered wheel disk or'tapered main body is designated 10. Itsradially extending peripheral portion of thickened cross section isdesignated 11, the integrally formed rim portion 12, the integrallyormed bead at the base of the thickened portion 13, and the reyconstructiom better because the bead at the base of this radially oneand the rim portion 1 1."

angularly continuous. In the form of Figs. 3 I

and 4, the portion 11 and bead 13 are discontinuous, being extended fora limited distance on'opposite sides of the studs and nuts 16, as clearlappears in Fi 3, and as is to be presume from Fig. 4 11 both cases, theintegrally extended rim 12 and the complemental of thickened crosssection.

rim portion 14 and itsfflange 15 are likewise mill may varyconsiderably. The origina rolling of parts 10, 11, 12 and 13 may berelied upon to give them substantially their final form.- But preferablythey are rolled partly toward final form or substantially all the wetoward final cross section. There- I after, t ey are given the propercontours by die' stamping operations. In such case the head 13 and theportion of thickened cross section 17 are utilized for clamping inthecentering and holding down portions of the dies, therebypreventing thestrain of the die operation on the rim portion 12 from beingcommunicated to such a degree to the reduced cross section of the mainbody 10 of the disk as to unduly strain or distort the same. Thecomplemental rim portion '14 may be formed in any of the wn' ways offorming rim section .v

, But beyond enteringinto the advantages as outlined, the thickenedcross section '11 and its associated bead 13 strgriigthen the periph--e? of the wheel mark y' in the region w era the demountablecomplementary rim section 14 must be secured in place. Thereby,

the wheel is made stifier, stronger, sturdier,

the same. Yet further it provides a very'or radial strain from the anyloosening of I namental appearance for the joint between the parts.

Flg. 5 shows the flange 15 of the rim sec tion 14 of outwardly convexform, as in the 'Michelin disk wheels. This provides a bet ter seatingfor the n-flange and more secure fastening of the nuts.

My invention, like all others, is susceptible of modifications which areto be comprehended in the annexed claim. I

What I claim and desire to protect by Let'- ters Patent is:

A vehicle wheel comprising a tapered disk having a thickened ortionadjacent its outer peri hery, said thic ened outer periphery bemg ent toform a portion of a rim section, a bead formed integrally with thethickened portion and forming a seat for a complemental rim portion,said complemental rim portion being seated against said bead andremovably secured to said integral disk and mm.

In testimony whereof I hereunto aflix my signature.
